Urban Flood Analysis Model for Plain Tidal River Network Region
Abstract Urban flood analysis is complicated in plain river network regions. In this paper, river network drainage unit model was proposed to simplify simulation of flood routing for small tributaries in river network and their flood control projects regulation, in which river network drainage unit was defined as an enclosed region surrounded by main river or embankment. Simplified model was applied to calculate municipal drainage system drain according to unit of drainage district and its capacity. Through coupling river network drainage model, municipal drainage model, flood routing model, and considering tide affection to rivers, urban flood analysis model for plain tidal river network region was built. Puxi flood control protected area of Shanghai was taken as an example to carry demonstration research. Flood caused by upstream river flood, storm surge, and local rainfall, and affected by flood control projects schedule was analyzed. The results show that simulated tide (water) level hydrographs were consistent with observed data. Overflow occurred at Suzhou River, Dianpu River and West Daying River, which agreed with the facts.
